Hi Joe,
   Method method = clazz.getMethod(DOM_LEVEL3_METHOD);
is equivalent to
   Method method = clazz.getMethod(DOM_LEVEL3_METHOD, new Class<?>[0]);
so you allocate an empty array each time you call getMethod.

A better patch is to cast null to Class<?>[] (or Object[] for invoke)
    Method method = clazz.getMethod(DOM_LEVEL3_METHOD, (Class<?>[])null);
